The Synthesis and Biological Activity of 9- and 2′-cAMP 7-Deoxypaclitaxel Analogues from 5-Cinnamoyltriacetyltaxicin-I.
2010
Abstract The synthesis and biological activity of new 7-deoxypaclitaxel analogues 3 and 4 in which the hydroxy group at C-2′ of the side-chain, C-9 and C-10 in the B-ring are substituted by cAMP and benozoyloxy group respectively are presented. These derivatives have been first synthesized from a natural taxoid 5-cinnamoyltriacetyltaxicin-I 5 and tested in vitro for cytotoxicity against three human tumor cell lines. The biologically tested results indicate 3 having more potent cytotoxicity and 4 having a remarkably reduced cytotoxicity as well as 33 having no much effect on cytotoxicity against all human tumor cell lines tested in comparison to that of paclitaxel.
